Replacement of Bluetooth antenna on CUH-1200 Ps4

I apparently have a Ps4 that has only two screws holding together the case. With that said It has become apparent that there are some changes to the system that differ from the tutorial here on how to replace the Bluetooth antenna. So I am reluctant to proceed with the instructions on the replacing it for fear of damage to the console. Can anyone please tell me the proper steps in carrying on the repair from removing the two screws? Any help would be much appreciated.

Thank you,
